INVENTOF! ATTORNEY Patented Oct. V 25, 1932 LOUIS EMANS, OF WILLMAR,MINNESOTA PORTABLE HOT WATER HEATER Application filed May 9, 1930.Serial Not 451,184.

This invention relates to a portable hot water heater, the generalObject of the mvention being to provide means whereby a heater can beeasily transported from oneroom or the like to another, with meanswhereby the heater will quickly heat the room or place in which it islocated.

Another object of the invention is to provide means for circulatingwater through a radiator from a tank where the water is heated, with afan for driving air through the radiator so that the air will be heatedand distributed to the room or place where the device is located.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like or'corresponding parts throughout the several views, and in which Figure 1is a vertical sectional view through the device.

Figure 2 is a section on line 22 of Figure 1.

Figure 3 is a rear View of the device.

Figure 4 is a bottom plan view thereof.

Figure 5 is a vertical sectional view showing the device placed in ahousing.

Figure 6 is a section on line 66 of Figure 5.

In these drawings, the numeral 1 indicates a circular casing which hasits bottom 2 spaced from the lower end of the casing so as to provide aheat receiving chamber 3 below the bottom and a water chamber 4 abovethe bottom. Tubes 5 have their ends passing through the bottom 2, thetubes being curved and passing through the sides of the chamber 4 sothat heated air from a burner or the from the casing 1 by the members 6,this like on which the casing is placed will pass through the tubes andthus heat the water in the chamber 4.

A casing A is supported in spaced relation casing A being made in theform of a radiator, with the upper receiving chamber 7, the lowerchamber 8 and the intermediate chamber 9 which connects the chambers 7and 8 together. Horizontal tubes 10 pass through the chamber 9 withtheir ends opening out through the front and rear walls of the chamberso that the water passing from the chamber 7 will flow around the tubesto reach the chamber 8.

A'motor driven fan 11 is arranged in an extension A at the rear of thecasing A so that this fan will force air through the tubes and thus theair will be heated by the water passing through the device. A tube 12has its lower end connected with the top of the chamber 4 at the rearthereof and its upper end is connected with a chamber 7. A tube 13connects the chamber 8 with the chamber 4, the tube extending to a pointadjacent the bottom of the chamber 4 so that the cooled water, afterpassing through the radiator, will enter the chamber 4 adjacent thebottom thereof and then fiow between the tubes 5 to the rear of thechamber 4 so that the water will be heated and thus rise in the tube 12and reach the chamber 7 from which the water will flow between the tubes10 back to the chamber 8. The chamber 7 is formed with a fillingspout'14 which is covered by a cap 15. Y 1

Figures 5 and 6 show the device enclosed in a housing 16 which is formedwith an opening 17 in its front to expose the front part of theradiator, with partitions 18 in the rear of the housing for causing airpassing through a hole in the rear wall of the housing to be drawn bythe fan through the passage formed by the partitions 18 and then forcedthrough the tubes by the fan. The products of combustion from the burner20 placed under the device will flow through the passages 21 formed bythe'partitions 18 and escaping through the chimney 22 attached to thetop of the housing. This housing is used when a gas burner or the likeis used for heating the water in the chamber'e so that the fumes fromthe burner will not enter the room. -When other types of heating meansare used which do not give oil? fumes, it is not necessary to use thehousing. It will, of course, be understood that electric heating meansmay be used to heat the water in the chamber 4 and in this case, thetubes 5 would not be used.

From the foregoing it will be seen that I have provided a portableheater for hot water which can be easily transported from one place toanother and in which the heat from the water is used to heat air forcedthrough the device by a fan so that the heated air is distributed to allparts of a room. This device requires very little fuel to heat the sameand is so compact that it can be placed over a single gas burner. Theupkeep is small as the only wearing part is the motor. The working partsare easily accessible so that they can e readily repaired or cleaned.

water chamber above, a plurality of heat circulating tubes openinthrough the bottom, a water radiator earned by the casing andcommunicating with said water chamber therein at its bottom and topportions, a fan carried by the radiator rearwardly thereof to confrontthe same, and a circulating tube leading from the top of the radiator tothe said water chamber in the casing, said radiator being provided witha vented core centrally thereof and confronting the fan.

In testimony whereof I aiiix my signature.

LOUIS EMANS.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readil apparent.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts,

provided that such changes fall within the scope of the appended claims.

What I claim is 1. A water heater oi the kind described comprising acasing havinga bottom inset from its lowermost edge to, provide a heatreceiving chamber below the same and also a water chamber above, aplurality of heat circulating tubes opening through the bottom, 21 waterradiator carried by the casing and communicating with said water chambertherein at its bottom and top portions, and a fan carried by theradiator rearwardly thereof to confront the same.

2. A water heater of the kind described comprising a casing having abottom inset from its lowermost edge to provide a heat receiving chamberbelow the same and also a water chamber above, a plurality of heatcirculating tubes opening through the bottom, a water radiator carriedby the casing and communicating with said water chamber thereinat itsbottom and top portions, a fan carried by the radiator rearwardlythereof to confront the same, and a circulating tube leading from thetop of the radiator to the said water chamber in the casin 3. A waterheater of the kin described comprising a casing having a bottom insetfrom its lowermost edge to provide a heat receiving chamber below thesame and also a.
